BCN3D+ Bed fixation ( anti vibration fixing piece, using the nylon screws ).

thingiverse

I'd like to have you print it using ABS material, as this will help minimize vibration on bed 8 when securing both trays with the three nylon screws. I've also fixed the bottom tray in place using superglue, while a nylon screw inserted through the hole will further reduce lateral movement caused by the elastic springs at high speeds.
